available. This figure fell below the initial sales of the previous games, such as 1.5 million and 500,000 units in first-week sales for Guitar Hero III: Legends of Rock and Guitar Hero World Tour, respectively. Combined sales in North America of Warriors of Rock and DJ Hero 2 were below one million in 2010, 63% below the total sales of Guitar Hero 5, DJ Hero, and Band Hero in 2009. Weak sales of Warriors of Rock, in part, led to Activision shuttering its Guitar Hero business unit in February 2011 and cancelling a planned 2011 sequel. As a result of the closure, no further downloadable content was created following the February 2011 packs.
